This invention relatesto levels and par?V tic-,ularly to an improved combination level havingas an object to provide a :simple construction while providing l,agdevi'ce which may be used in a. number olf dilerent ways. Another. object of the invention is to pro- `vide an vimproved form ,of level formed to -act at `one 'time `as a line level, another time .as a surface :level and another tiune :as an angle finder.

A 'further object, f1-nere`specific-ally,V the Aprovision of ale-vel structure wherein two `level elements are used, one "being positioned to remain in horizontal plane and the other jpositioned .tobe swung to different vangles lfrom a horizontal plane; 1in thea'ccoinpanyi'ng drawingv Figure 1 isa sidevv'ie'w yof a level disclose- `ingan embodiment of lthe invention, A 'g Figure 2 is a tozp plain 'view-:of thelevel showninFgure y y Figure 3` is a sectional view through Figure l online 3-3.

Figure 4 is a fragmentary view of one end of the level showing the opposite side to that the device may be suspended on a `wire or other line. l Figure 5 is a sectional view through Figure 4 on line' 5 5. i vlieferring to ythe vaccompanying drawing by numerals, 1 indicates abase which may be of wood or other material and which vhas a lower flat surface 2 adapted to rest on an object when the level is in use. Co-acting with the base 1 is an auxiliary base 3 having a flat surface 4 which falls in the plane of t-he surface 2 when thel device is on a planey surface. y Clo-acting with the bases 1 and 3 are level members 5 and 6. Member 5 is 4.provided with a leg 7 having a foot 8 secured to base 1 by a screw9 or other suitable means. Leg 7 near'the upper part merges into a socket 10 having arms 11 connected together by a-suitable rivet 12, said v rivet passing through the casing 13, said icasing carrying the'transparent member 14 in which the' liquid and air bubble are positioned the same presenting a level vial. "o The casing 13 is cut away at 15 for disclosing-part of member 14 whereby the air bubble may be readily observed at any t1me. Preferablyintegral with'the socket 10 is an extension 16 bent-for forming a hook 17 whereby vthe device may be supported on a line, as for instance, line 18. Thelev'el memillustrated in Figure 1 and illustrating how the surface- 4 would be :screw 2,7,l The leg 25 is alsolpro-vided with y v `pointei- 28 with or maybe lseparate and .rigidly ygseycured in Eplace. k'llhe socket 21 is lprovided which may. be integral there Vwith V,an integr-al extension 29y which )fits 75 y,over .theleztension 2,4 and isiclamped'thereto by ,a bolt30,havingzagwingnut`31. Ihe vclamping action of thisbolt may lock thel parts firmly together or may merely hold Y so l the parts together so that they willvnot ac#l cidentally move, .thoughthe parts arel capable of movement by ymanually shifting one partr in respect to the other. The extension 29 is provided with a dial 32 having'a number of graduations 33 which co-act with the 35 pointer 28 for indicatingk the position ofthe level members 5 and 65er rather indicate the Vcondition of one level member in respect to the other.y V Y 5 e 'l As shown in Figure 1, the pointer 28de opposite zero and this indicatesthat the level ymember 6` is iny directline with the level member y5. Ifdesired, level member 5 with its base 1, could beleft in the position shown inv Figure-1 and'y levelmember 6 swung upwardly toa forty-five degree angle. This angle would be indicated by the fact that `the dial 32 moves with the extension 29 and,

consequently, would move the graduations 45 opposite pointer 28. When the parts are adjusted to this po'sitiomthe wing nutf31 could be operated for firmly clamping the parts `together so that the surface 2 would be, for instance, in' a k'horizontal plane and yat forty-five degrees ico `to a horizontall'plane. 1n this way, an accurate angle'y may be secured for sawing boards or for laying out structural work. It is, of course, evident that the level '6 could be shifted to Vother angles'without departing. from the spirit of the invention.

When the device is tov be used as aline level, members 5 and 6 are moved to a position in alignment oruntil pointer 28 is op` posite zero. The Wing nut 3l is then tightened until the parts are suiiciently clamped together to act as a unit. The hooks 17 at each end of the device are then fitted over the Wire or other line. By observing the position of the bubble in the respective members 5 and V6, the level of the line may be readily determined.

What I claim is:

1. A combination level comprising a pair of tubular members eachcarrying level vials, a pair of supporting legsfor one of said tubular members, asingle supporting leg for the other of said tubular members, means for pivotally connecting together said tubular members so that the tubular member carrying'the single leg may be swung at an angle to the other tubular member, and a base connected with the tWo legs associated With one of the tubular members.

2. A level comprising a base, a tubular member,y a pair of legs connected With said tubular ymember and With said base, said tubular member having` a notch at one point, a level vial in said tubular member and eX- posed through said notch, a pointer Von one ov said legs, an auxiliary tubular member constructed substantially identical AWith the posite end of the leg to said base, said tubular member having a notch at'one point, alevel vial in said tubular member exposed through said notch, a point-er on one of said legs, an auxiliary tubular member con structed substantially identical with the first mentioned tubular member pivotally connected thereto at one end, a leg connected to the free end of said auxiliary' tubular member formed with a line receiving hook substantially identical in form With the first' mentioned hook, a dial mounted on one end of said auxiliary tubular member (3o-acting vwith said pointer for indicating the relative angular position of the auxiliary tubular member, and means for locking the tubular member and the auxiliary tubular member movement.
